Application filed May 27,1918. Serial No. 236,767.

To all whom it may concern:

Be it known that I, PETER M. KNUDSEN, a subject of the King of Norway, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Marble- Projectors, of which the following is a full, clear, and exact specification.

This invention relates to devices for projecting marbles, and has for its object to provide a simplified and improved device,

of this kind for use by children to shoot marbles at one another without making the fingers sore.

It is the aim of this invention to make the shooter or projector as simple as possible in construction, and to this end only one piece of resilient metal is employed. Another object is to make the device more durable than others of the same nature heretofore used, and this is accomplished by forming a double bend where the metal strip is folded upon itself to provide the resilient hinge for the projector arms. A further object is to prevent the marble from slipping out from between the arms or jaws of the pro-v jector in a lateral or other than a directly forward direction, and this is done by providing the edges of said jaws with turned over lateral edges forming beads or ridges along the edges of said jaws over which the marble cannot ride in ordinary use. Other objects will appear as the description proceeds.

The invention will be first hereinafter described in connection with the accompanying drawings, which constitute part of this specification, and then more specifically defined in the claims at the end of the description.

In the accompanying drawings, wherein similar reference characters are used to designate corresponding parts throughout the several views Figure 1 is a plan view of the metal strip of which the projector is made as it appears after its lateral edges are turned over but before said strip as a whole is bent into the form of a shooter.

Fig. 2 is a section on the line II-II of Fig. 1.

Fig. 3 is a perspective view showing how the device is held in the hand and operated,

Fig. 4 is a side view of the device bent into shape for use, and

Fig. 5 is an end view of the same, showing the position of a marble between the aws. a

Patented Sept. 24, 1918.

The projector is made of a single piece A of resilient metal 1, which first has itslateral edges turned over upon its body portion to form beads or ridges 2,- as shown in Figs. 1 and 2. The metal strip 1 is then bent into the form shown in Fig. 4: with a double bend 3, serving as a spring hinge for the projecting arms or jaws 4 and 5. The lower jaw preferably extends in line with the bottom member of the double bend 3, while the up per jaw 5 may be bent upwardly at an angle to the upper member of said double bend, as shown, so as to discharge the marble 6 are pressed together at a point adjacent to or slightly in advance of the double bend,

as indicated in Fig. 3.

The jaws 4: and 5 may be curved transversely, as at 7, Fig. 5, to fit generally around the marble. The beads 2 are turned inward, as shown in this figure, and serve to retain the marble against accidental discharge in a lateral direction, thus insuring a straight shot to the front each time the projector is used. The heads 2 also extend throughout the length of the metal strip 1, and they provide reinforcement to the double bend 3, making said bend or spring hinge much more durable and eflicient than it would be without such beads.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. A marble projector comprising a strlp of resilient metal having its intermediate portion formed into a double bend and its extremities extending beyond said bend to form marble gripping jaws.

2. A marble projector comprising a strip of resilient metal having itslateral edges turned over to form beads, said strip being bent to form opposed marble gripping aws each having said beads along its lateral curved transversely to substantially fit around the marble and having ,aibead along each edge for thepurpose specified.

4. A marble projector comprising a strip of resilient metal having beads throughout its lateral edges, sai'd 'striphaving its intermediate portion formed into a doublebend With the beads along the edges of said portion reinforcing the bend, and the extremities of the strip projecting beyond the bend 10 to form inarble gripfiing jaws each having the beads along theirinner' faces for the pur- Wilmington, D. 0."
